Optical photographic lens assembly

An optical photographic lens assembly, comprising a lens group and at least one spacing element, wherein

• the lens group comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens, which are sequentially arranged from an object side to an image side along an optical axis;
• there is an air gap between any two adjacent lenses among the first lens to the seventh lens;
• the first lens to the seventh lens comprise at least one aspheric lens;
• there are seven lenses having refractive powers in the optical photographic lens assembly;
• the at least one spacing element comprises:
• a fourth spacing element, located between the fourth lens and the fifth lens and in contact with an image-side surface of the fourth lens;
• the optical photographic lens assembly satisfies:
